Hello,

I searched for about half an hour but my google-fu isn't strong apparently. Please tell me how to interpret the "2019.0002" rating on the coupled inductor in the input EMI filter portion as shown in the schematic I've attached. Thank you!

Thanks a lot Albert. From what I'm reading then, this is a common mode connected pi-filter, which means the effective inductance offered would be equal to (L+M)/2 = L
